(...)a recently graduated researcher at Harvard who set out to test the privacy paradox.
  His conclusion: We do care about our privacy, even if we don’t always act in our best interests.

FYI: This is the privacy paradox. The author seems to assume it means that people just don't care...which wouldn't be paradox. No, the idea is that people rate privacy very high or even place a lot of value in it in sandbox behavior experiments, like the one described in the article. Thus it is surprising how people then behave "in the wild", There are a lot of theories about the Why, which I recommend you to read up upon if interested.

It would help and also show professionalism IMO if the author wouldn't just link other oversimplified articles from NYT when quoting science...
